The written informed consent form (WICF): factors that interfere with acceptance.

Background: The written informed consent form (WICF) provides information that must be written in simple, easily understood language, highlighting voluntary participation safeguards, risks, possible benefits, and procedures. Currently, the possibility that research subjects do not fully understand the text of the WICF or their rights as participants, despite having signed the WICF and agreed to participate in the study, has been a point of discussion.

Aim: To evaluate the readability of the WICFs, as well as to correlate research subject acceptance of the WICF with demographic status, social factors, risk-benefit relationship, and education level.
